Application filed October 1, 1919. Serial No. 327,684.

To (ZZZ w 7mm it may 0077.06772 Be it known that I, GEORGE C. BAKER, a citizen of the United States, residing at Bayonne, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Boiler Constructions; and I do hereby declare the following to be a full, clear and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved boiler and one object of the invention is to provide a boiler so constructed that the water passing through the tubes may be very thoroughly heated and caused to circulate though the water tubes and drum during the heating process and further to so construct this boiler that the products of combustion from the furnace may be very efliciently directed upon the water tubes and guided in their passage through the boiler.

Another object of the invention is to provide a boiler which will have a relatively large water capacity but which will be compact in structure.

Another object of the invention is to so construct this boiler that it will have a very strong construction and which will permit of expansion and contraction.

Another object of the invention is to provide improved means for supporting the boiler tubes and water heads in the frame of the boiler. 1

This invention is illustrated in the accompanying drawings wherein:

Figure 1 is a view in elevation showing the improved boiler construction with the wall construction removed.

Fig. 2 is a top plan view of the improved boiler.

Fig. 3 is a vertical sectional view through the boiler.

Fig. l is a view similar to Fig. 1 showing a modified construction.

Fig. 5 is a vertical sectional view through the type of boiler disclosedin Fig. 4.

This boiler includes a frame having vertical posts or standards 10 which are formed of steel and support I-beams 11 which are also formed of steel. The inner I-beam 12 rests upon blocks 13 which rest upon the crossheads or I-beams 14: carried by the inner standards 15. These cross heads 14 in addition to carrying the blocks 13 also carry saddles or bolsters 16 upon which rests the drum 17. The walls 18 may be formed of brick, poured concrete or cement, or of any suitable material which will inclose the boiler and retain the products of combustion therein. The top or cover sections 19 may be formed of a sheeting of asbestos or any suitable material and a filling 20 will be provided between the inner I-beams 12. It will thus be seen that with this construction there will be provided a body or boiler housing which will be very strong and durable due to the frame of steel construction. This boiler will of course be provided with the inlet 21 through which products of combustion from the furnace may pass into the boiler and will be further provided with an outlet 22 through which the products of combustion may pass to a suitable chimney or smoke stack. A damper 23 may be provided in the outlet to control the passage of the products of combustion to the boiler. An upwardly flared baffle indicated in general by the numeral 24 is provided in this boiler and extends longitudinally in the central portion thereof between the standards 15 so that flames and other products of combustion entering the boiler through the inlet 21 will be directed upwardly and caused to pass over this baffle. A second baffle 25 is positioned in the boiler to the rear of the bal'lle 24 so that the flames and gases will be directed downwardly toward the bottom of the boiler after passing over the bafiie 24: and then pass upwardly beneath the baffle plate 25 in order to reach the outlet 22.

The boiler tubes or water tubes 26 extend vertically in the forward and rear portions of this boiler between the upper and lower water heads 27 and 28 which extend longitudinally of the boiler as shown in Fig. 2. Manifold pipes or mains 29 which are in communication with the feed water pipes 30, have communication with the upper water head 27 in the rear portion of the boiler through the medium of nipples 31 and are provided with dividing walls or baffle plates 32 so that the water entering the mains 29 will only pass partially through the same and will then enter the water heads and pass downwardly through the water tubes 26 connected therewith. Branch pipes 33 lead from the drum 17 and communicate with the outer end portions of the mains 29 so that hot water from the drum may mix with the cold water entering the mains and thus cause this cold water to be partially heated through mixing with the hot water. The inner end portions of these manifolds are connected by a pipe ormain 34 which has communication with thedrum through the medium of the nipple 35 thus permitting hot water from the drum to pass. into the rear portions of these mains and into the water head 27 communicating therewith. This hot water will pass downreadily seen that the cold water which has been slightly heated from mixing with water from the drum will enter the settling drums 36 and will mix with the hot water which passes down into the same from the drum 17 and therefore the water which passes out of the forward end portion of the settling drum into the pipes or water tubes 26 extending through the forward portion of the boiler will be warm and therefore the flame and other products of combustion which heat the Water tubes will have a very efficient, action since the water will already be partially heated when entering the pipes first engaged by these products of combustion. This heated water passes upwardly through the tubes 26 in the forward portion of the boiler after entering the lower water heads 28 thereof which are in communication with the settling drums and will enter the upper water heads and pass out of the same through the nipples'38 into the mains or manifolds 39 which are connected by a main 40 from which extends nipples 41 com 'municating wlth the drum 17. From an 1nspection of Fig. 3, the circulation of the water through this boiler can be readily followed.

' In order to support the'structure just described, there has been provided U-bolts 42 which fit about the upper end portions of the water tubes 26 and extend upwardly between the nipples 31 and 38 and between the inner end portions of the water heads 27 and through supporting plates 43 carried by I-beams 44 which rest upon the L beams 11 and 12. These U-bolts 42 correspond to the U-bolts 45 shown in Fig. 5 and extend through plates 46 which extend longitudinally of the drums and are supported by I-beams 47 carried by standards 48 and resting upon the cross heads 14. In the form shown in Fig. 5 the upper water heads 49 extend transversely of the drumi-nstead of longitudinally thereof as in the. form shown in Fig. 2 and may be provided with fiat side faces or may be corrugated so that they will have interlocking engagement.

they will pass down through the communieating pipes 26 and. return to the forward end portions of the lower rear water heads. The water passes from the water heads 52 into the settling drum 55 and from this drum to the pipes 56 and 57 into the forward and rear end portions of the lower water heads 58in the forward portion of the boiler. The water will then pass up through the water tubes and into the upper water heads 59 from which extend pipes ornipples 60 communicating with the drum 17 Similar nipples 61 connect the drum with the water heads 49 so that hot water-in the chuni' may pass into the heads 49 and down through i the pipes 26 leading therefrom to mix with the water just entering these heads; From an inspection of Fig. 5it will be seen that the flame and other products of combustion entering the boiler will pass up through the forward portion thereof over the baffle 62 and will then pass downwardly beneath the superheater 63 which is of a conventional construction and after passing beneath the superheater and depending bailie 64, will P P the bafiie 54 and down through T 7 he outlet 22.

From the above description it. can be readily seen that in a'boiler constructed as shown and described, the water passing through the water tubes and upper and lower heads: will be very effectively operated upon and thoroughly heated, this heating being assisted due to the fact that water which has already been heated will be mixed with cooler water passing through the boiler and thus the water permitted to be heated very rapidly.

What is claimed is: 1 r 1. 'Arboiler including a frame structure, a

drum carried by the frame structure, verti cally extending water tubes positioned in the frame upon opposite sides of the drum 'and arranged in front and rear sets, lower ice water heads communicating with the tubes and arranged in front and rear sets, conduit 7 means communicating with the'lower water heads for delivering water fromlthe rear water heads and provided with outlet means upper water heads communicating with the sets of water .heads to; the 'forwardsets of r for withdrawal of waterfrom the boiler,

tubes and arranged in front and rear sets, and conduits communicating with the upper water heads and with the drum whereby water may pass from the upper front set of water heads to the drum and from the drum to the upper rear set of water heads of the rear tubes.

2. In a boiler construction, a frame, a drum carried by the frame, water tubes extending vertically through the frame on 0pposite sides of the drum, front and rear lower water heads connected with the tubes and having inner and outer end portions, a settling drum communicating with the inner end portions of the lower water heads, a conduit leading from the settling drum and having communication with the forward end portions of the forward water heads, partitions in the rear lower water heads for preventing direct passage of water through the same, and upper water heads communicating with the water tubes and having communication with the drum.

3. In a boiler construction, a frame, a drum carried by the frame, vertically extending water tubes positioned in front of and to the rear of the drum, front and rear lower water heads communicating with the tubes, conduit means for conducting water from the rear water heads to the forward water heads, upper water heads communieating with the upper ends of the tubes, manifold pipes having communication with the upper water heads in front of the drum, a main connecting the inner end portions of the manifold pipes and having communication with the drum, manifold pipes having communication with the upper water heads to the rear of the drum and having water inlets communicating with their outer ends, partitions in the last mentioned manifold pipes and positioned at points intermediate their length, a main connecting the inner end portions of the last mentioned manifold pipes and communicating with the drum, and branch pipes leading from the drum and communicating with the last mentioned manifold pipes at points intermediate the partitions thereof and outer ends thereof.

In testimony whereof I afiix my signature in presence of two witnesses.
